进口蝶式止回阀详细说明,用途/结构,报价
【进口蝶式止回阀】详细说明:
蝶式止回阀是指依靠介质本身流动而自动开、闭阀瓣,用来防止介质倒流的阀门,又称逆止阀、单向阀、逆流阀、和背压阀。止回阀属于一种自动阀门,其主要作用是防止介质倒流、防止泵及驱动电动机反转,以及容器介质的泄放。止回阀还可用于给其中的压力可能升至超过系统压的辅助系统提供补给的管路上。止回阀主要可分为旋启式止回阀(依***旋转)、升降式止回阀(沿轴线移动)、蝶式止回阀(沿中心旋转)。
Butterfly check valve refers to the valve that automatically opens and closes the disc depending on the flow of the medium itself to prevent medium backflow, also known as check valve, one-way valve, counterflow valve, and back pressure valve. Check valve is an automatic valve. Its main function is to prevent medium backflow, reverse pump and drive motor, and release of container medium. Check valves can also be used in pipelines to supply auxiliary systems where pressure may rise above system pressure. Check valves can be divided into swing check valves (rotating according to the center of gr***ity), lift check valves (moving along the axis), butterfly check valves (rotating along the center).
【进口蝶式止回阀】用途:
蝶式止回阀用于纯净管路及工业、环保、水处理、高层建筑给排水管路,阻止介质逆向流动之用。该止回阀采用对夹式,蝶板为两个半圆,且采用弹簧强制复位,密封面可为本体堆焊耐磨材料或衬橡胶,使用范围广,密封可靠。
【进口蝶式止回阀】结构说明:
一、蝶式止回阀的阀瓣呈圆盘状,绕阀座通道的转轴作旋转运动,因阀内通道成流线型,流动阻力比升蝶式止回阀小,适用于低流速和流动不常变化的大口径场合,但不宜用于脉动流,其密封性能不及升降式。蝶式止回阀分单瓣式、双瓣式和多瓣式三种,这三种形式主要按阀门口径来分,目的是为了防止介质停止流动或倒流时,减弱水力冲击。
二、蝶式止回阀:依阀瓣工作形式分为两种:1、阀瓣沿着阀体垂直中心线滑动的止回阀,蝶式止回阀只能安装在水平管道上,在高压小口径止回阀上阀瓣可采用圆球。蝶式止回阀的阀体形状与截止阀一样(可与截止阀通用),因此它的流体阻力系数较大。其结构与截止阀相似,阀体和阀瓣与截止阀相同。阀瓣上部和阀盖下部加工有导向套简,阀瓣导向简可在阀盏导向简内自由升降,当介质顺流时,阀瓣靠介质推力开启,当介质停流时,阀瓣靠自垂降落在阀座上,起阻止介质逆流作用。直通式蝶式止回阀介质进出口通道方向与阀座通道方向垂直;立式升降式止回阀,其介质进出口通道方向与阀座通道方向相同,其流动阻力较直通式小;2、阀瓣围绕阀座内的销轴旋转的止回阀。蝶式止回阀结构简单,只能安装在水平管道上,密封性较差。
三、管道式止回阀:阀瓣沿着阀体中心线滑动的阀门。管道式止回阀是新出现的一种阀门,它的体积小,重量较轻,加工工艺性好,是止回阀发展方向之一。但流体阻力系数比旋启式止回阀略大。
